  • What does GID mean? - Unix Linux Stack Exchange
    What does GID actually mean? I have Googled it and this is what linux about com said: Group identification number for the process Valid group numbers are given in etc group, and in the GID fie
  • Created a group with existing gid, now cannot delete it
    Maybe your sysadms devised the gid numbering scheme where assigned central gids are assigned going doing from 1000 (where non-system uids start) to avoid clashing with system ones, but now Ubuntu starts using those two
  • How to get the primary group of a user? - Unix Linux Stack Exchange
    Group ID (GID) The Group ID (GID) is a number used to uniquely identify the primary group that the user belongs to Groups are a mechanism for controlling access to resources based on a user's GID rather than their UID This can significantly reduce the size of some configuration files and allows users to be members of more than one group
  • Change gid of a specific group - Unix Linux Stack Exchange
    The GID is the primary identifier of the group As far as the system is concerned, a different GID is a different group So to change the GID, you're going to have to modify all the places where that GID is used You should avoid treating the GID as significant and use group names instead; you can change the name of a group with a single command (on Linux: groupmod -n NEW_GROUP_NAME OLD_GROUP
  • gid - How to pick a static group id? - Unix Linux Stack Exchange
    I am tasked with reassigning a static group id (gid) to an existing group name that exists on multiple Linux servers E g the group name foo currently exists on multiple servers, but with differen
  • ssh - Is it possible to create multiple users on Linux with the same . . .
    The ArchWiki - rsnapshot page mentions creating multiple users with uid and gid set to 0 as a means of creating users that login remotely to perform backups One thing you can do to mitigate the potential damage from a backup server breach is to create alternate users on the client machines with uid and gid set to 0, but with a more restrictive
  • How do sudo permission bits influence (e)uid and (e)gid?
    As long as there is no the set-group-ID bit, how is it possible sudo and ps, being executed by it, are running under the root gid and egid? Haven't checked its source code, but a process running as root (i e , with root's uid) can just set its own gid to whatever it wants So, the setgid property would be inconsequential How is it possible sudo and ps both have their uids changed? You seem to
  • GID, current, primary, supplementary, effective and real group IDs?
    You mix two different distinctions here: Between real and effective group ids Between primary and supplementary users' groups The first distinction refers to how processes are being run Normally, when you run a command program, it is run with the privileges of your user It has the real group id same as your user's primary group This can be changed by a process in order to perform some tasks
  • Why cant I create a user with primary GID 100? - Unix Linux Stack . . .
    Why does the RHEL installer (and presumably any other currently), not allow you to set that user's primary GID at install time to gid=100? I have the assumption it is ok to have some ~50+ local users on the system defined in etc passwd all having a gid of 100 users Is there any downside to this? What is the convention and history of gid 100
  • x-systemd. automount and noauto causes CIFS mount to ignore uid gid and . . .
    The issue was resolved with the help of @waltinator, who suggested using the auto,_netdev options With those in place, the network share now mounts correctly at boot with the proper permissions That said, I'm still curious: Why does using noauto,x-systemd automount instead of _netdev result in the mount being owned by root, or cause it to ignore the specified user and permission options?
